Tip:Cinema 4D R20 cannot load scenes that were saved in Cinema 4D R4-R12. Open such scenes with Release 19, for example, and save them so they can be opened in R20. Visit labs.maxon.net for more solutions regarding such issues.

Tip:Older plug-ins that were not created to work with Cinema 4D R20 will not work in R20. Please contact the respective plug-in developer for more information.

Tip:If you encounter unusual display effects in the Viewport, check your monitor’s profile settings (main menu: Edit | Preferences | View | Display Color Profile). If color management is disabled it can lead to a faulty display in the Viewport. Either load your own color profile or use sRGB.

Tip:Make sure not to modify the installed program folders or their contents in any way (the only exception: The plugins folder - plugins can be placed here as usual)! If any modifications are made your software will not function properly! All user-specific information is saved to the user directory, including Content Browser libraries and similar elements.

Tip:Cinema 4D starts in Hardware OpenGL mode. If you experience Hardware OpenGL problems (i.e., a problem with the graphics card), quit Cinema 4D and restart Cinema 4D with the Ctrl/Cmd key held down until the messages Shift+Ctrl: Set Shading to Software Mode appears. If you want to activate Hardware OpenGL again (e.g., with new drivers or a new graphics card), you can do so here: main menu: Edit | Preferences | OpenGL | Use Hardware OpenGL.

If you receive error messages (e.g., "Cannot open file") when importing files from foreign formats (e.g., *.csv files in the Structure Manager), this file might already be open in a different application. This program will prevent the file from being opened in Cinema 4D. Close that application (e.g., Excel) prior to importing the file into Cinema 4D.
